ENGLEWOOD, Colo. — Peyton Manning lofted a pass down the left side of the Denver Broncos practice field Sunday and barely had to watch it as landed in Demaryius Thomas' hands.

Thomas had split two defensive backs and, though a whistle blew, didn't slow, sprinting 30 more yards to the end zone. As he turned around to make his way back to the huddle, he turned to a group of observers and smiled.

"They didn't make that tackle," Thomas said.

It was the type of play that Thomas made over and over in private workouts this spring with an elite group of NFL wide receivers, including Calvin Johnson and A.J. Green.

"I want to be one of those guys that isn't forgotten once I'm done. That's my main thing," Thomas told USA TODAY Sports.

Wide receivers, perhaps more than players at other positions, make their mark through statistics. Yet Thomas is preparing for the possibility that his individual numbers might go down in 2013 from the 94 catches and 1,434 yards and 10 touchdowns he recorded last season.

This is Thomas' new challenge in Denver, balancing the desire to become one of the game's elite wide receivers while sharing an offensive huddle with other big-name talents in Wes Welker and Eric Decker

But Thomas is the true No.1 receiver, the one with the best combination of size (6-3 and 229 pounds), power to throw a vicious stiff-arm and speed to outrun just about any NFL defensive back.

Gase coached quarterbacks for Detroit in 2007 when the Lions used the No.2 draft pick on Johnson. He whole-heartedly approves of his new star pupil spending his offseason training with Johnson. As Thomas develops as a route-runner (he had a limited base to work with when he arrived from Georgia Tech) Gase hopes other parts of Johnson's game are rubbing off on Thomas.

"The one thing from my experience around Calvin was just how he had the confidence to just go and get the ball," Gase said. "That's the one thing I'm sure (Thomas) is trying to work on, stretching the field and just being able to attack the ball. It's not an easy thing to do. You've got a guy draped on you and you're trying to catch while running full-speed. It's one thing you've got to develop and fight through some of the frustrations so that can happen."

Thomas was a redshirt freshman at Georgia Tech in 2006 when Johnson was in his final collegiate season. Thomas was the tag-along kid brother who watched everything Johnson did, and then tried to do the same.

"I'm trying to be better than him, and I'm trying to get where he's at, because I feel like he's the best in the game," Thomas said.

Seven years later, it hasn't changed all that much, though Thomas has certainly begun to close the gap between him and his mentor.

"Him, A.J. (Green), the guys we work out, those guys are trying to come get me, trying to be the top in the league, as they should," Johnson said last week about Thomas.

While working out in Atlanta and Los Angeles, where he caught passes from New York Jets' quarterback Mark Sanchez and went through cardio sessions on the beach, Thomas dropped nearly nine pounds and weighed in at 226 pounds when he arrived for training camp. He's hoping to play at 222 pounds this season, and said he already feels faster.

His teammates notice a difference.

"When he goes out here to work, you would think he had never made a catch in his life, or he's a free agent or something," said teammate Andre Caldwell. "He's a big guy, but has the speed of a little guy, and when he gets the ball, we call him 'Juggernaut' (based on the X-Men character) because he can't be tackled."

Love it when fellow Bronco fans have nothing better to do than to insult me.

On topic. Demaryius is on the cusp of having an epic season, Manning has never had a receiver the caliber of Thomas. Look for him to shatter all previous receiving records and be placed in the patheon of alltime Bronco greats.
